As a result of the Department of Energy (DOE) examination of 4,031,160 additional pages of publicly available records accessioned by the National Archives and Records Administration (NARA), the Department discovered an additional 515 documents containing 1193 pages ofRD and FRD which were inadvertently released: Additional Pages Number of Documents Number of Pages Number of Number of Pages Examined Since with RD/FRD in the Documents Pages RD FRD Last Report 4,031,160 515 9,191 339 854 The identified documents are in collections belonging to the Department of State and the Department of the Army. The 515 documents were inadvertently declassified and made available to the public in DELETED by the Department of State and NARA. No classified documents of the DOE or its predecessor organizations were inadvertently released. The documents inadvertently released contained the following types of RD and FRD information: RD FRD - Mass or dimensions of fissile materials - Stockpile quantities - Tampers and initiators - Storage locations - Boosting systems - Storage capacities - Detonation systems - Costs of weapons and components - High explosives - Nuclear 'weapon yields - Weapon/device output and performance - Delivery system accuracy - Weapon reliability - Height and depth of burst - Nuclear weapon materials - Yield select capability - Gaseous diffusion technology - Nuclear test information - Naval nuclear propulsion information - Nuclear safing systems - Fusion weapon research - Designs of arming and fuzing systems Improper markings in 307 of the 515 documents for classification level (e.g., Secret), classification category (e.g., RD), and/or automatic classification level downgrading occurred when the documents were originated or later during the documents' lifetime. The improper marking ofthe documents for classification level, classification category, and/or downgrading may have contributed to the inadvertent release of documents. UNCLASSIFIED 2 UNCLASSIFIED The Department of State, the Department of the Army and NARA have been afforded an opportunity to review their specific documents containing the RD and FRD information. The 515 documents have been withdrawn from public access and protected in accordance with DOE requirements. The inadvertently released nuclear weapons design information (RD) detailed in this report concerns the early generations of nuclear weapons that this country developed in the 1950s and 1960s. Potential adversaries, emerging proliferant nations and terrorist groups aggressively target U.S. nuclear weapon information. Information regarding older nuclear weapons is of significant value since it is often technically less sophisticated. These designs would be most readily used by a would-be nuclear proliferant to obtain its first nuclear weapon. The inadvertently released nuclear weapons utilization information (FRD) detailed in this report could assist potential adversaries in assessing the strength of the U. S. nuclear arsenal. Additionally, inadvertently released information on deployments of nuclear weapons outside the United States may violate international agreements and harm diplomatic ties with foreign host nations. The inadvertently released naval nuclear propulsion information (also RD) addressed in this report could assist adversaries in the development of nuclear propulsion systems for their submarines and surface ships. The training of other agency reviewers continues to reduce the rate at which Restricted Data and Formerly Restricted Data are improperly declassified. DOE and NARA are working to better integrate their efforts to more quickly identify and safeguard documents potentially containing RD and FRD. All records that may contain RD and FRD are removed from public access. Details of the specific inadvertent releases are contained in the attached classified appendix.
